As easy as breathing

When I came in this morning Michael was reading a magazine and holding it with both hands. He was unable to use his right hand until today. He also wasn't able to lift his hands towards his face until today!
We played hangman. Today was the first day he was awake for most of the day. We joked around and I laughed.
He keeps asking, "when can I go home?" I tell him he has to be able to breathe and to sit up.
The lyrics to a song are "loving you is an easy as breathing". Until this experience, I thought that was a love song. Now that I see how difficult breathing is, I am not so sure.
